What is the best type of valve to use for throttling or frequent opening and closing?

The globe valve is particularly well-suited for throttling purposes due to its design, which allows for precise flow control. The internal structure of a globe valve includes a movable disk and a stationary ring seat, which enables it to adjust the flow rate effectively. This allows operators to finely tune water or fluid flow, making it ideal for tasks that require regular adjustment of the flow.

In addition to its throttling capability, globe valves can also perform effectively during frequent opening and closing operations without sustaining excessive wear. This resilience ensures long-term reliability in various applications where control over flow is essential.

Other types of valves, such as the ball valve, while efficient for quick shut-off, are not as effective for regulating flow. Gate valves are designed mainly for on/off control and are not suited for throttling, as they can suffer from vibration and flow turbulence when partially open. Check valves serve an entirely different purpose, allowing fluid to flow in one direction only, without the capability for regulated flow control or throttling. Therefore, the globe valve stands out as the most appropriate choice for applications that require both throttling and frequent operation.
